【问题描述】：
我尝试更新对等依赖项，但完成后，我不再能够编译我的 Angular 应用程序。我得到的输出是：
Compiling @angular/material/core : es2015 as esm2015
Compiling @angular/material/expansion : es2015 as esm2015
Compiling @angular/router : es2015 as esm2015
Compiling ngx-plyr : es2015 as esm2015

我已尝试删除节点模块并重新安装它们。 我已经尝试更新到最新的 cli 版本。 我已尝试按照this 错误报告中的说明预运行 ngcc。 我已经尝试禁用和重新启用 Angular Ivy。
任何帮助将不胜感激。如果您需要任何进一步的信息，请告诉我，我很乐意提供。

我猜你的插件 ngx-plyr 还没有为 Angular Ivy 做好准备。因此，您可以禁用 Ivy，降级到 Angular 8（甚至可能 9 个作品？）或使用另一个库来包含 Plyr。此外，提及日志文件
